Specification of Letters Patent.

Patented Nov. 10, 1914.

State of Indiana, have made an Improve.

ment in Steel Barges or 5cows, of which the following is aspecification,

My invention"isan'imprcvement in the class of barges, floats or scowswhich are employed in connection with steamshovels or diggers, and areconstructed with a flat top for reception and transportation of dirt orother material. It is particularly important that such barges or scowsshall be com structed with special reference to lightness and rigidity,and particularly with adapte tion for separation of parts or sections inorder to facilitate the removal from place to place, and especially forloading and transportation on platform cars or on boats.

With these ends in view I have devised and constructed a scow whichpractical experience has demonstrated to meet all requirements. It ismade of plate or sheet steel and in sections which may be easily securedtogether or detached from each other as conditions require. The jointsbetween the separable parts are provided with rubber or equivalentgaskets which render it water-tight.

The invention is also distinguished by the special form and constructionof angle-iron for bracing, supporting and connecting fiat sections orsheets.

In the accompanying drawings, Figure 1 is a top or plan view of thebarge. Fig. 2 is a side view. Fig. 3 is an enlarged section on the line3-3 of Fig. 1. Fig. 45 is in part an end view and in part an end sectionof the barge. Fig. 5 is a longitudinal vertical section of the barge.Fig. 6 is a perspective view of an end portion of the barge constructedand prepared for attachment to another corresponding section. Fig. 7 isan enlarged vertical section on the line 77 of Fig. 6. Fig. 8 is anenlarged section on the line 8-8 of Fig. 2. Fig. 9 is a cross section onthe line 9-9 of Fig. 8'. Fig. 10 is a plan view of two end sections ofthe barge placed with their inner ends juxtaposed and ready to beadjusted and secured together to form a complete barge hull. (A portionof the left hand section is broken out to show the arrangement of thebulk-heads.)

- in tying the top and bottom parts together.

The barge is an oblong, rectangular body having a flat top, and asbefore intimated, is constructed of plate or sheet steel for the purposeof combining lightness, strength, rigidity and durability. In formingthe top of the barge, a series of rectangular plates or sheets 1 (seeFigs. 1, 3,- 6,) are arranged edge to edge and secured by screw bolts totransverse channel bars or girders 2 which extend between the sides ofthe barge. Angle-iron bars 3 are bolted to the side edges of said plates1 and extend from end to end of the barge. v

The bottom of the barge is similarly formed. of plates or sheets 4-which are bolted to, and strengthened by, transverse angle bars orgirders, 5, as shown in Figs.- 5, 6, l4, 1 l6. Other angle bars 6 arearranged with one flange underlying the side edges of the plates 4 andthe ends of the transverse hgirders 5, and all are bolted tb-FTS gether.T e -vertical sides or side panels oir the barge are formed of plates 7and strengthening angle bars 8, one flange of which is riveted to theplates and the other extends laterally, as shown best in Fig. 6. It willbe noted that the ends of these bars 8 are flush with the top and bottomof the barge. By this construction a very light but a very strong andrigid structure is formed, and the lateral projection of the flanges ofthe bars 8 offers no material hindranceto progress of the barge throughwatergwllich is always necessarily very slow.

In Fig. 7, which represents an enlarged angle bars 3 are shown overlyinthe top plates 1 and the angle bars 6 are shown imderlying the bottomplates. Thus the bars 6' form supports for the bottom pro-per of thebarge, and they are in turn attached to thevertical side plates 7 andthe bars or girders 8. It will be that the latter serve a very importantpurpose not only in strengthening the structure as a whole, but

In order to impart further longitudinal rigidity to the barge,bulkhead-s or longitudin al girders 9 are provided (see Fig. 6)

and also angle-iron girders 10, shown in the same figure.

The girders 9 are spaced apart in the middle longitudinal portion of thebarge and angle-irons 9 are attached to the lower edges of girdersproper and rest upon and are bolted'to short angle iron pieces 10 whichare in turn secured to the transverse angleirons or girders 5. Similarangle iron bars 9" are attached to the top edge of the girders 9 andupon these rest the transverse angle-iron bars 2 forming a part of thetop of the barge.

By the construction, arrangement, and combination of parts so fardescribed, it is apparent that the different portions or sections of thebarge may be detached from each other when required for convenience ofstorage or transportation from one place to another by means of carts.cars, or boats. In certain cases. however. it is desirable to separatethe hull into large sections, and for this purpose I have adopted thestructure hereinafter described.

As will be understood by reference to Fig. 10, the central bulk-heads 9.the top angle bars 10 and the bottom angle bars 6 together with thebottom plates e extend beyond the main body of the barge, and as will beunderstood by reference to Fig. 10, the other section or. end portion ofthe barge is correspondingly constructed: that is to say, its topportion is extended beyond the bottom portion and its longitudinalbulkheads or girders 9 are extended beyond the bottom. Thus, when thetwo end sections of the bars which are shown juxta-posed in Fig. 10, arepushed together, the bottom part of the right hand section wilLprojectunder the top portion of the left hand section and the ends of thegirders 9 and an le bars 6 and 10 will come in contact.v 'fhe endsof therespective bulk-heads are provided with angle iron abutments 9 whichmeet and are bolted together, as will be better understood by referenceto Fig. 10. In like manner the angle irons 6. see Fig. 8, which areattached to the ends of the bottom plate or sheets 4:, are juxtaposedand bolted together. In other words, abutments formed by angle irons 6abut when the two end sections of the barge are brou ht together. Tostrengthen the ioint thus ormed I apply a short angle piece 11 (seeFigs. '6 and 8), one flange of the same underlying the parts 6 6, andsupporting them while the other is applied to the side flanges of thesame. Thus the two grand sections of the hull may be separated from eachother at a central point, or the hull may be, on the same principle,divided into a greater number of sections. In any event, the hull tweenthe adjacent parts which are ordinarily submerged in the water. Thegaskets are indicated in Figs. 6, 7, 8, and 9 and their furtherdescription is not required.

I claim:

1. A steel barge formed of plates or sheets arranged at top, bottom, andsides, vertical angle bars bolted to the sides, and longitudinal anglebars arranged at the bottom angle of the barge, one flange underlyingthe bottom plates, and the other flange being arranged inside the sideplates and bolted to the latter and. also to the vertical angle bars, asdescribed.

2. A steel barge formed of plates or sheets arranged at top, .bottom andsides, transverse angle bars traversing the bottom, longitudinal anglebars arranged at the ends of the bottom plates and such transverse bars,and one flange of the same underlying said bottom plates and bars.vertical angle bars secured to the sides. their inner flanges beingbolted to the vertical flange of the aforesaid longitudinal angle bars,as described, the longitudinal bars being thus arranged inside the sideplates, as specified.

3. A steel barge comprising separable grand sections each formed ofplates or sheets arranged at top, bottom and sides, and longitudinalangle bars arranged at the upper and lower angles of the barge, otherangle bars attached to the sides and also to the transverse edge of thebottom late, the edge angle bars of each section eing adapted to formabutments for corresponding portions of the other detachable bargesection, a portion of one section projecting or overlapping the oppositeportion of the other section, as described.

4. A barge comprising grand separable sections,; each formed of top.bottom and side plates, one section having a short top portion andprojecting bulkhead, and the other having a corresponding proiecting topportion and bulkhead, the top and bottom and bulkheads having abuttingend portions, and means for securing the grand sections detachablytogether, as described.
